Using AdMob Mediation

  1. How does percentage allocation work?

    As of May 20, 2013, percentage allocation for mediation placements has been deprecated. Existing mediation placements using percentage allocation will continue to serve, but you can no longer set percentage allocation for a new placement.

    You can set the percentage of total ad requests you'd like to send to each ad network. As your app sends new ad requests, AdMob Mediation divides them among your ad networks based on the percentages you specified. As new requests come in, it continually recalculates how to divide them into these percentages. That way no network falls behind its specified percentage.

    Disabled ad networks or ad networks with 0% traffic allocated to them will not receive ad requests.

  2. Where's AdMob Mediation in the AdMob interface?

    Under the Sites & Apps tab, select Ad Network Mediation.
  3. How does eCPM allocation work?

    eCPM is an estimate of the revenue you receive for every thousand ad impressions. For more information, see this help article.

    You can allocate traffic to your ad networks by eCPM. When you allocate by eCPM, AdMob Mediation sends your app's ad request to the network with the highest eCPM value. If that ad network is unable to fill the request, AdMob Mediation tries whichever network has the next highest eCPM. It continues down the list until it finds a network to fill the request or it's tried all your chosen networks.

    You can also localize your eCPM values: you can set different values for different countries or regions. That way AdMob Mediation allocates traffic to the network that has the highest eCPM value given the particular location of each request. For example, you might get a higher eCPM when a particular ad network serves a request in Japan. You might therefore want to set a separate eCPM value for Japanese ad requests handled by this network.

    Disabled ad networks or ad networks with $0.00 eCPM will not receive ad requests.

  4. What happens if no ad networks can return an ad?

    If there is a current ad, it remains on screen. If there is no current ad, the ad view is transparent and users see whatever is behind the ad view.

    See our code level documentation for Android and iOS for more details.

  5. Can I allocate traffic to House Ad campaigns?

    Yes! AdMob Mediation allocates traffic to your House Ad campaigns using the same rules you set for the ad networks in your mediation placement. These rules are based on eCPM, percentage, and location. The option to add AdMob House Ads appears right in your list of mobile networks. See the steps below.

  6. How to allocate traffic to House Ad campaigns

    1. Set up your AdMob House Ads. Make sure your House Ad campaign targets the site ID associated with the specific app you're configuring for ad network mediation.
      If you're new to AdMob House Ads, see our House Ads guide.
    2. AdMob House Ads appears in your list of ad networks. Select AdMob House Ads and click continue
    3. Enter the site ID associated with the app you want to target with your House Ads campaign.
    4. When your app sends an ad request, AdMob Mediation contacts your enabled ad networks in an order based on your traffic allocation settings. If the first network can't fill the ad request, it moves on to the next network. If AdMob Mediation reaches AdMob House Ads, it allocates the ad request to your House Ads campaigns.
    5. Upon receiving an ad request, your House Ads campaigns return an ad if:
      • At least one campaign targets your app's associated ID.
      • At least one campaign is eligible and currently active (i.e., it hasn't reached its impression limit, and it hasn't been paused or ended).
      • An ad in an active, eligible campaign meets the criteria of the ad request.
    6. If for any reason your House Ads fail to return an ad, AdMob Mediation will continue down the list of your ad networks.
  7. Which site ID should I use for the AdMob network?

    It's usually best to use the site ID associated with the specific app that you've configured for mediation. If you need to set up a new mediation placement, create a new site placement and use that site ID.

  8. Where can I view revenue reports?

    On the Sites & Apps Reporting page. Sign in to your ad network's website to view revenue data from other ad networks.

  9. How do I make changes to my AdMob Mediation settings?

    1. Under the Sites & Apps tab, select Ad Network Mediation.
    2. Hover over the placement you'd like to adjust and click "Manage Settings".
    3. Here you can update your eCPM values or adjust your percentage allocations. You can also enable or disable ad networks. Your changes don't require you to make any code updates to your app.
    4. Click Save once you are done making changes.
    You can make changes to your AdMob Mediation settings at any time.

Payment

  1. Is AdMob Mediation free?

    Yes! AdMob Mediation is an entirely free service. We believe in a well-connected mobile community.

  2. Does AdMob Mediation take a cut of the revenue that I get from the ad networks?

    No. Everything about AdMob Mediation is free.

  3. How do I get paid?

    You receive payments directly from the ad networks you work with.

Features and improvements

  1. How does AdMob Mediation improve on AdWhirl?

    Here are a few of the improved capabilities in AdMob Mediation:

    • More ad formats on more platforms: AdMob Mediation mediates interstitial formats and tablet-size formats on both Android and iOS.
    • Network-level reporting: Nearly all AdMob reporting is also available through AdMob Mediation. Even better, you can narrow your reporting down to individual ad networks.
    • Country-level allocation: You can localize your eCPM values by setting different values for different countries or regions. That way AdMob Mediation allocates traffic to the network that has the highest eCPM value given the particular location of each request. For example, you might get a higher eCPM when a particular ad network serves a request in Japan. You might therefore want to set a separate eCPM value for Japanese ad requests handled by this network.
    • Google scalability and infrastructure: Unlike AdWhirl, AdMob Mediation is built on the Google stack. That means you benefit from the reliable uptime and continued growth that Google offers for all its products.
    • Updates and support: As we continue to innovate new methods of ad network mediation, we’ll update AdMob Mediation and add new features. AdWhirl will remain live and functional, but we’ll no longer update and support it.
  2. Do I need to switch over from AdWhirl?

    You don't need to, but we strongly recommend it. AdMob Mediation offers improved reporting, targeting, and integration. It does everything AdWhirl does—the difference is that AdMob Mediation does it better. Plus, only AdMob Mediation will offer new features.

    AdWhirl will remain live and functional, but we will no longer update it or offer product support. As we continue to innovate better methods of ad network mediation, the difference between these two products will only increase.

  3. Which ad sizes does AdMob Mediation support?

    AdMob Mediation supports the following ad sizes:

    • banner (typically 320x50)
    • medium rectangle (typically 320x250)
    • full banner (typically 468x60)
    • leaderboard (typically 728x90)
    • skyscraper (typically 120 x 600)
    • interstitial (full screen)
  4. Which ad networks are available in AdMob Mediation?

    AdMob Mediation currently works with Adfonic, AdMob, BrightRoll, HUNT Mobile Ads, iAd, InMobi, Jumptap, Millennial, and MobFox. Don't see your favorite ad network? Support for more ad networks is coming soon!

  5. Are there any available networks specific to my region?

    Yes, many of the networks listed above are strong in specific regions. Please see the partner pages for details on these networks.

  6. I have an app that produces a lot of traffic. Can you handle me?

    Absolutely. We built AdMob Mediation to handle massive amounts of traffic. Many apps that use it generate millions of impressions a day. Scalability is no problem here.

AdMob eCPM Floor Beta

  1. What is the AdMob eCPM Floor Beta?

    We are running a beta to allow publishers to set a CPM floor for AdMob ads which appear in their apps. Ads will be returned if the per-impression auction produces a CPM expected to be above the floor, otherwise the request will not fill.

  2. How does AdMob eCPM floor work?

    The AdMob auction, like AdWords, is run on a per-impression basis. Because most advertisers bid on clicks (CPC), we predict the expected CPM (eCPM) for each impression based on the likelihood (pCTR) that the winning ad will be clicked. When a publisher specifies a floor we will aim to meet that floor for the ads we return, but it is not guaranteed.

  3. Why is eCPM floor in beta?

    We want to see how this feature performs at scale. Also, at this time we do not guarantee that we can meet the CPM floor that has been set by the publisher.

  4. Is there a limit to how high the CPM can be set?

    No, but if a publisher chooses a very high CPM then it decreases the likelihood of that request being filled. Publishers should monitor fill rates.

  5. Can I use eCPM floor with non-AdMob mediation solutions?

    We're testing this as part of the beta, but it's not widely available to all publishers. If you are eligible for this test then your Google account manager will contact you.

  6. How does eCPM floor affect house ads?

    House ads are unaffected. We don't apply any eCPM floor to house ads, so they will continue to serve as normal.

  7. How long will the eCPM Floor Beta run?

    Long enough for us to gather feedback. We reserve the right to terminate the beta at any time. If we terminate the beta, we will remove the floors from all AdMob placements for beta pubs, and fill rates will rise.

  8. What values should I set for AdMob eCPM floor?

    We recommend experimenting with different values to obtain the best overall monetization from all your mediation networks. However, a good starting configuration is to set the floor just above the eCPM of the next highest network.

  9. How does eCPM floor work with other ad networks during mediation?

    AdMob network will continue to make requests in the order of the highest eCPM to lowest eCPM. The eCPM floor only applies to the AdMob eCPM Floor Beta network. For all other ad network line items, please continue to supply eCPMs based on historical averages.

  10. How will setting an eCPM floor affect my fill rate?

    Your fill rate may decline depending on how high you set the eCPM floor. We recommend experimenting with different values for the eCPM floor to tune your eCPM and fill rates to your liking.

  11. How do I view my eCPM floor reporting?

    Go to the Sites & Apps Reporting page and filter by the publisher ID you used when setting up the AdMob eCPM Floor Beta network.
